Abstract

WIDESPREAD ocean floor unconformities around Australia have been explained by nondeposition of sediment and erosion by deep-sea currents, which undoubtedly occurred. The irregular duration of their hiatuses is in contrast to the widespread, brief but regularly terminated, early Oligocene unconformity on the continent. It is suggested here that the Palaeogene unconformities in Australia and the surrounding ocean basins have been derived from two different and possibly unrelated causes.
